Opera doesn't correctly understand file types

[GoogleCodeExporter]

BROWSER(S): OPERA 11.52+
OS : Windows XP
PLUGIN VERSION: 1.47
JQUERY VERSION: 1.7.1

With that code :
<input type="file" class="multi" accept="gif|jpg|jpeg|png|bmp" maxlength="3" 
name="my_field[]"/>

In Opera you can choose type files as "gif" "jpg" "bmp(*.*)" but it doesn't 
display any file and "png" is missing. Only "All files (*.*)" works.

I fixed it by adding a pipe ("|") before the file types, like :
<input type="file" class="multi" accept="{if (mb_eregi('opera', 
$_SERVER['HTTP_USER_AGENT'])}|{/if}gif|jpg|jpeg|png|bmp" maxlength="3" 
name="my_field[]"/>

Then, Opera will diplay all files by default (no more other choices), and it 
doesn't disturb the plugin with file type JS verification.
